Solution Overview

Problem

Conventional milling drums in tanneries face issues with high energy consumption due to low thermal efficiency, excessive water and chemical use, and the emission of potentially harmful fumes and vapors, necessitating costly extraction equipment.

Innovation Solution

A machine with a controlled-atmosphere environment and insulation features maintains optimal temperature and humidity, uses minimal water and chemicals, recycles excess liquids, and incorporates a condensation system to capture and purify vapors, ensuring hermetic sealing to prevent emissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by stationary object

If conventional milling drums are used for leather processing, then the processing function is provided, but high energy consumption occurs due to low thermal efficiency

Engineering Contradiction:

Improveenergy consumptionVSAvoidthermal efficiency

Core Design Contradiction:

Use of energy by stationary objectVSLoss of energy

Solution Approach 1:

The patent changes the material parameter of the drum enclosure from conventional materials (wood, steel, plastic) to transparent material with high thermal insulation properties. This parameter change simultaneously improves thermal efficiency (reducing energy loss) and enables visual monitoring of the processing operation

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The drum enclosure uses composite construction with transparent insulating material that combines optical transparency with thermal insulation properties. This composite material approach resolves the contradiction by providing both low energy consumption and high thermal efficiency

Inventive Principle:

Principle #40Composite materials

2Object-generated harmful factors

If conventional milling drums are used, then leather processing is performed, but harmful fumes and vapors are emitted into the environment

Engineering Contradiction:

Improveharmful emissionsVSAvoidenvironmental pollution

Core Design Contradiction:

Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful fumes and vapors into a beneficial resource by condensing them and recovering useful substances. The condensation system transforms waste emissions into recoverable materials, eliminating environmental pollution while potentially recovering valuable chemicals

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The drum enclosure creates a controlled, sealed environment that prevents harmful substances from escaping into the atmosphere. The transparent enclosure with condensation system maintains an inert containment zone where emissions are captured and neutralized rather than released

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

3Quantity of substance

If conventional milling drums are used, then processing operations are conducted, but large amounts of water and chemicals are consumed

Engineering Contradiction:

Improvewater and chemical consumptionVSAvoidwaste water and chemicals

Core Design Contradiction:

Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent implements a recovery system that captures and recycles water and chemicals from the processing operation. The condensation and collection system prevents loss of valuable substances by recovering them for reuse, thereby reducing both consumption and waste

Inventive Principle:

Principle #34Discarding and recovering

4Strength

If conventional milling drums with solid enclosure are used, then structural strength is maintained, but thermal efficiency is low

Engineering Contradiction:

Improvestructural strengthVSAvoidthermal efficiency

Core Design Contradiction:

StrengthVSLoss of energy

Solution Approach 1:

The patent changes the material parameters of the enclosure to achieve optimal thermal performance while maintaining structural strength. The transparent insulating material is selected to provide both mechanical adequacy and superior thermal properties compared to conventional opaque materials

Inventive Principle:

Principle #35Parameter changes
